As a first step in the project of ratchet optimisation, the optimal driving waveform among a wide class of admissible functions for an overdamped, adiabatic rocking ratchet is shown to be dichotomous. ‘Optimum’ is defined as that which achieves the maximum (or minimum negative) average particle velocity. Implications for the design of ratchets, for example… (More)
